Description

  The present invention relates to an information processing apparatus, an information processing method, and a program for performing a copy process by a touch operation on a touch panel.

  In recent years, a device having a touch panel including a display unit and a touch input unit has appeared, and a user can perform processing by an intuitive operation through a UI (User Interface) by a touch operation. For example, an operation process such as copy or paste can be performed by performing a touch operation on an object indicating a file or the like displayed on the screen of the display device.

  For example, in Patent Document 1, when one finger touches a display object to perform a pinch-out operation and the touch distance between the two fingers exceeds a predetermined value, the display object indicates An apparatus for copying content data is described.

JP 2011-170785 A

  The touch operation is intuitive and easy to understand for the user, but if the touch operation and the types of processing corresponding to the touch operation increase, the operation will be a completely different process with a slight difference in operation. The number of cases that end up increases. For example, in the case of Patent Document 1, a pinch-out operation with two fingers is generally a display enlargement process, and erroneous operations of the enlargement process and the copy operation may frequently occur.

  In view of such a situation, an object of the present invention is to provide an information processing apparatus, an information processing method, and a program that are less likely to cause an erroneous operation in a touch operation and that can perform the operation accurately.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 is an external view showing a table display which is an information processing apparatus according to the present invention. FIG. 2 is a functional block diagram showing an example of this table display.

  The table display 10 includes a display device 20 as a touch panel on the entire surface of the table, and a plurality of users perform a touch operation while watching the display to perform processing. The display device 20 has a structure including a touch input unit 22 on the upper side of a display unit 21 such as a liquid crystal panel.

  The table display 10 includes a display control unit 30 that performs display control on the display unit 21, a storage unit 40 that stores data, and a control unit 50 that controls processing according to operations from the touch input unit 22.

  The control unit 50 includes a touch detection unit 51 that detects a touch position from an input signal of the touch input unit 22, a touch area calculation unit 52 that calculates a touch area of a touched region from the detected touch position, and a detection by the touch detection unit 51. An operation determination unit 53 that determines a touch operation from the result and the touch area by the touch area calculation unit 52, and an operation processing execution unit 54 that executes an operation process based on the determined touch operation.

  The operation determination unit 53 determines an operation mode from a touch operation such as touch-down, touch-up, flick, pinch-in, and pinch-out, the number of touches, and the like. Here, the touchdown is to touch the touch input unit 22 with a hand or the like, and the touch detection unit 51 detects the position as a new touch. The touch-up is to release a touched hand from the touch input unit 22, and the touch detection unit 51 detects a position where the touch disappears.

The table display 10 can deal with various touch operations. In particular, a copy operation will be described.
The copy operation is to perform a copy process when the object displayed on the display unit 21 is touched at two places and one touch is pinched out.
In Patent Document 1 described as the background art, a pinch-out operation with a finger is a copy operation. However, in this embodiment, a pinch-out operation using a palm is used, and a general enlargement operation in the pinch-out operation is performed. It is something to distinguish.

<Embodiment 1>
First, in the first embodiment, the touchdown operation is a copy operation and related operations, which will be described in detail below.
FIG. 3 is a flowchart illustrating the entire operation process according to the first embodiment.

  For example, as illustrated in FIG. 4, it is assumed that the operation target object 100 is displayed on the display unit 21 of the display device 20. When the user performs touch input on the surface of the display device 20, the touch detection unit 51 of the control unit 50 detects the touch position based on the input signal of the touch input unit 22 (step S1). And the operation determination part 53 of the control part 50 determines whether it is touch-up operation or touch-down operation from the detection result of the touch detection part 51 (step S2). In the case of touchdown, the process proceeds to operation determination processing A in step S3. In the case of touch-up, the process proceeds to operation determination process B in step S4. And the operation process execution part 54 of the control part 50 performs a process based on an operation determination result (step S5).

FIG. 5 is a flowchart showing the procedure of the operation determination process A.
The touch area calculation unit 52 of the control unit 50 calculates the touch area of the touch region from the detection result of the touch detection unit 51 (step S11). The operation determination unit 53 of the control unit 50 determines whether a part or all of the touch area is within the area of the operation target object 100 displayed on the display unit 21 (step S12). If it is not within the object 100 to be operated, the process ends. If it is within the object region to be operated, the process proceeds to step S13, and it is determined whether or not there is a touch with a touch area equal to or larger than a preset threshold in the object region. If there is no touch, the process ends.

Here, it is assumed that the input is performed with the finger of the hand and the palm of the hand, and a predetermined area for identifying “finger touch” and “palm touch” is set in advance as a threshold value. A touch area equal to or greater than the threshold is defined as “palm touch”, and a touch area less than the threshold is defined as “finger touch”.
In this embodiment, touch input by hand is used. However, touch input by a pen and input by a stamp having a large area may be used. Anyway, any touch can be used as long as the touch can be identified by two types.

  The operation determination unit 53 determines whether or not there are three or more touches in the object area to be operated (step S14). If there are three or more touches, the operation determination unit 53 determines the copy prohibit mode (step S15). The copy prohibit mode is a mode in which copy processing is not performed. This is a case where there are three palm touches 111, 112, and 113 in the area of the object 100 as shown in FIG.

  Otherwise, the operation determination unit 53 determines whether there are two touches in the object area to be operated (step S16), and if there are two touches, determines that the copy mode is set (step S17). The copy mode is a mode for performing a copy process. This is a case where there are two palm touches 111 and 112 in the area of the object 100 as shown in FIG.

Otherwise, the operation determination unit 53 determines that there is one touch within the object area to be operated (step S18), and determines that the object operation prohibition mode is set (step S19). The object operation prohibition mode is a mode in which operation processing such as movement, rotation, and enlargement / reduction is not performed on an object. For example, as shown in FIG. 8, there is one place of the palm touch 111 in the area of the object 100.
Since it is a touch-down touch operation, the number of touches cannot be zero, and thus the process ends.

FIG. 9 is a flowchart showing a processing procedure of the operation determination processing B.
Since the operation determination process B is a touch-up operation, the touch position, touch area, and touch area are already known. After that, it is necessary to perform an operation determination by reducing the number of touch locations by touch-up.

  The operation determination unit 53 of the control unit 50 determines whether there is a touch whose touch area is equal to or greater than a preset threshold in the object region to be operated (step S21). If there is no touch, the process ends.

  The operation determination unit 53 of the control unit 50 determines whether or not there are three or more touches in the object area to be operated (step S22). If there are three or more touches, the copy determination mode is determined (step S23). . For example, as shown in FIG. 6, there are three touches on the palms 111, 112, and 113 even if there is a touch-up.

  Otherwise, the operation determination unit 53 determines whether there are two touches in the object area to be operated (step S24), and if there are two touches, the operation determination unit 53 determines the copy mode (step S25). For example, as shown in FIG. 10, the palm touch 113 is touched up, and the palms 111 and 112 remain in the area of the object 100.

  Otherwise, the operation determination unit 53 determines whether there is one touch within the object area to be operated (step S26). If there is one touch, the operation such as movement, rotation, enlargement / reduction, etc. of the object is performed. The prohibit mode is determined (step S27). For example, as shown in FIG. 11, the palm touch 112 is touched up, and the palm 111 remains in the area of the object 100.

  If the touch is not one place, the operation determination unit 53 determines that there is no touch (0 place) (step S28), and determines the object operation mode (step S29). The object operation mode is a mode that enables operations such as movement, rotation, and enlargement / reduction on an object. For example, as shown in FIG. 12, the palm touch 111 is touched up, and the palm does not remain in the area of the object 100.

FIG. 13 is a flowchart showing a processing procedure for executing the operation processing.
The operation process execution unit 54 of the control unit 50 executes a process based on the determination result of the operation determination unit 53.
The operation process execution unit 54 determines whether the operation determination is a copy mode (step S31). In the copy mode, the operation determination unit 53 determines whether one of the touches pinches out from the inside of the operation target object and touches up (step S32). For example, as shown in FIG. 14, the palm 112 in the object 100 is pinched out and comes out of the object 100, and touches up as shown in FIG.

  At this time, since the touch detection unit 51 detects the touch-up position, it outputs it to the operation processing execution unit 54 (step S33). The operation process execution unit 54 copies and stores the data indicated by the operation target object in a predetermined folder set in advance in the storage unit 40 (step S34). Then, the display control unit 30 copies and displays the object at the touch-up position (step S35). For example, as shown in FIG. 15, an object 200 that is a copy of the object 100 is displayed at a position where the palm 112 is touched up.

  If it is not the copy mode, processing such as another mode (copy inhibition mode, object operation inhibition mode, object operation mode) is executed (step S36).

<Embodiment 2>
In the first embodiment, all the touches are “palm touch”, but “finger touch” may be mixed.
As illustrated in FIG. 16, in the second embodiment, the “palm touch” is only the palm 111, and the other touches 112 and 113 are “finger touch”. Even in this case, the flowcharts of FIGS. 3, 5, 9, and 13 hold.

  If there is at least one “palm touch”, the operation determination unit 53 determines that the mode includes the copy mode in step S13 or step S21. The operation determination unit 53 determines each mode based on the number of touches, and the operation process execution unit 54 executes an operation process under each mode.

  For example, as illustrated in FIG. 17, when the palm 111 and the finger 112 are touched on the object 100, the operation determination unit 53 determines that the copy mode is selected because the two-point touch and the touch area of the palm is equal to or greater than the threshold. To do. Then, when the finger 112 pinches out of the object 100 and touches up as shown in FIG. 18, the object 200 that is a copy of the object 100 is displayed at the touch-up position as in FIG. In addition, the data indicated by the object 100 is copied and stored in a predetermined folder in the storage unit 40 as in the first embodiment.

  Here, the finger 112 is pinched out of the object, but the same copy processing is performed even if the palm 111 is pinched out of the object.

<Embodiment 3>
In the first and second embodiments, the copy process is performed by pinching out the finger touch or the palm touch, but in the third embodiment, the copy process is performed without pinching out.
For example, as shown in FIG. 7, when two palm touches are performed, the operation determination unit 53 determines that the copy mode is set, and performs a copy display of the object 100 at the position of the display unit 21 set in advance. It is good. In addition, the data indicated by the object 100 is copied and stored in a predetermined folder in the storage unit 40 as in the first embodiment.

  In this way, when the display object is touched with a touch area greater than or equal to the predetermined area, the operation determination unit determines that the operation includes the copy mode. Since the operation can be different depending on the two types of touches, it is possible to prevent erroneous operation and erroneous determination. For example, in a pinch-out operation, it is possible to clearly distinguish the operation processing such as enlargement when only finger touch is performed and only copy when palm touch is combined or finger touch and palm touch are combined. .

  In addition, by prohibiting copying at three or more places, even if an operation such as pinch out is mistakenly performed, copying is not performed, and erroneous determination can be prevented.

  The program that operates in each device of the information management system according to the present invention is a program (a program that causes a computer to function) that controls a CPU (Central Processing Unit) or the like so as to realize the functions of the above-described embodiments related to the present invention.
